Answer:
y = 2x + 8
6x + 3y = 19
6x + 3(2x + 8) = 19
6x + 6x + 24 = 19
12x = -5
x = -5/12
y = 2(-5/12) + 8
y = -5/6 + 48/6
y = 43/6
Answer:
y = 2/5x + 18.
Step-by-step explanation:
The line will have the same slope of 2/5.
Using the point-slope form of a line:
y - 12 = 2/5(x - -15)
y - 12 = 2/5(x + 15)
y = 2/5x + 6 + 12
y = 2/5x + 18.
The answer is 7.5.
7 4/8 is also 7.5
Well percents are probability, and probability is similar to theory. So i think its theoritical probability.
Hope this helps.
